Code Review
This pull request introduces several good changes to improve the reliability of the windowing tests. Wrapping the driver extension handler in a try-catch block and adding timeouts to awaitNotification and driver.waitFor are excellent measures to prevent tests from hanging and to improve error logging. The introduction of a _requestDataWithRetry helper on the test side is also a solid strategy to handle transient failures. My main feedback is to enhance the retry logic to also handle application-level errors returned from the driver extension, which will make the tests even more robust and easier to debug.
